Adopt international latest technology, uder innovative tech, strict QC, our independent R&D team synchronously adopt international craft and cast great quality harmonic drive reducer. With s-shaped teeth, our harmonic reducer with high precision, low noise and long life.

Features& Benefits With 10 years’ research of harmonic drive reducer, we master the core technology, adopt the latest international S-shape gear transmission mechanism for harmonic reducer. While maintaining the smoothness of the traditional involute tooth type, it can improve the performance of precision, strength, rigidity, service life and so on.

Four advantages of our Harmonic Reducer
1.S-shaped tooth
2.Long life
3.High precision
4.Low noise


S-shaped teeth of harmonic reducer
Compared with the traditional involute tooth, this product is manufactured by our self-developed S-shaped tooth process which can comprehensively improve the performance of precision, strength, Japanese torque amplifier speed reducer gearbox motor planetary gear set rigidity and service life.

Long Lifespanof harmonic reduce
With the S-shaped tooth manufacturing technology, the generator deformation required for gear occlusion is small, which reduces the concentrated stress on the bearing of the wave generator, and the service life of the whole machine can be as long as 10,000h.

High Precisionof harmonic reducer
Through the S-shaped tooth manufacturing process, the number of gear bites reaches one third of the total number of teeth, and the error is averaged, so that the position accuracy and turning accuracy can reach very high requirements.

Low Noiseof harmonic reducer
Through the S-type tooth manufacturing process, in the operation of harmonic reducer, the tooth surface contact is large, the slip speed is small, and there is no sudden change, so the operation is stable, no impact, low noise.
